Example species in this genus include Nototodarus sloanii, a species sought for human food; in the process of harvesting N. sloaniiAustralian sea lions are frequently killed, since that marine mammal preys upon this squid species.[3] Furthermore, New Zealand arrow squid, N. sloanii, is an important food source for the endangered yellow-eyed penguin, Megadyptes antipodes.[4]
